Description

本発明は、接合方法及びその方法で形成される成形部材に関する。 The present invention relates to a joining method and a molded member formed by the method.

繊維強化プラスチック及び熱硬化性樹脂を含む補強部材と金属材料とを接着し、補強された構造体を得る加工法が特許文献１に提案されている。例えば、熱硬化性樹脂に熱を与える金型を用いることで、補強部材は、予め成形された金属材料に接着される。この加工法から得られた構造体は高い機械的強度を有している。そのため、例えば車両の構造部品は、この方法でプレス成形されることで高い機械的強度を得る。 Patent Document 1 proposes a processing method for obtaining a reinforced structure by adhering a reinforcing member containing a fiber reinforced plastic and a thermosetting resin to a metal material. For example, by using a mold that applies heat to a thermosetting resin, the reinforcing member is adhered to a preformed metal material. The structure obtained by this processing method has high mechanical strength. Therefore, for example, a structural part of a vehicle is press-molded by this method to obtain high mechanical strength.

特許第６００５０８６号Patent No. 6005086

一方、加工に必要な工程数をできる限り最小にすることで、加工に必要な時間を減縮したいという要請がある。したがって、母材と補強部材の成形及び接合は同時に行われることが好ましい。しかし、補強部材が有する厚みが大きいほど、母材に与えられる形状に対応して、補強部材を同時に成形することは難しい。また、重量最適化のために、補強部材はできる限り軽量であることが好ましい。そのため、接合される補強部材が容易に変形可能で、また軽量であるように、接合される補強部材が有する厚みは１ｍｍ以下であることが好ましい。 On the other hand, there is a demand to reduce the time required for processing by minimizing the number of processes required for processing as much as possible. Therefore, it is preferable that the base metal and the reinforcing member are formed and joined at the same time. However, the larger the thickness of the reinforcing member, the more difficult it is to mold the reinforcing member at the same time corresponding to the shape given to the base material. Further, for weight optimization, it is preferable that the reinforcing member is as light as possible. Therefore, the thickness of the reinforcing member to be joined is preferably 1 mm or less so that the reinforcing member to be joined can be easily deformed and is lightweight.

さらに、機械的強度以外の材料特性、例えば大きな減衰能を母材に与えたいという要請がある。この要請に対し、補強部材と粘弾性素材を挟んだ状態で２つの部材を接合することで、大きな減衰能を有する複合材料が得られる。この複合材料を補強部材として母材と共に成形及び接合することで、形成される成形部材は大きな減衰能を得る。 Further, there is a demand for giving the base material material properties other than mechanical strength, for example, a large damping capacity. In response to this request, by joining the two members with the reinforcing member and the viscoelastic material sandwiched between them, a composite material having a large damping ability can be obtained. By molding and joining this composite material together with the base material as a reinforcing member, the formed molded member obtains a large damping ability.

そこで、本発明は、複合材料と被成形部材に形状を与えながら、複合材料と被成形部材を接合する方法、及びその方法で形成される成形部材を提供することを目的とする。 Therefore, an object of the present invention is to provide a method of joining a composite material and a member to be molded while giving a shape to the composite material and the member to be molded, and a molding member formed by the method.

［１．成形装置］
図１は、本発明の実施形態に係るプレス成形装置１００の概略構成を示す。プレス成形装置１００は、複合材料と被成形部材に形状を与えながら、複合材料と被成形部材を接合する成形装置である。 [1. Molding equipment]
FIG. 1 shows a schematic configuration of a press forming apparatus 100 according to an embodiment of the present invention. The press molding apparatus 100 is a molding apparatus that joins a composite material and a member to be molded while giving a shape to the composite material and the member to be molded.

［１．１：成形装置の概要］
図１に示すように、プレス成形装置１００は、概略、下部構造１０と、該下部構造１０の上に配置された上部構造１２を有する。 [1.1: Outline of molding equipment]
As shown in FIG. 1, the press forming apparatus 100 generally has a lower structure 10 and an upper structure 12 arranged on the lower structure 10.

下部構造１０は、図１の手前側から奥側に向かって伸びる、上向きの凹形状を略中央部に有する直方体形状の剛性の高いダイス１４を備える。このダイス１４は、該ダイス１４の上面に配置される後述する被成形部材１１０と複合材料１１２に所定の形状を与える、上向きに凹形状の型部１６と、該被成形部材１１０の端部を固定する治具（例えばバイス）を有する（図示せず）。 The lower structure 10 includes a rectangular parallelepiped-shaped highly rigid die 14 having an upward concave shape in a substantially central portion extending from the front side to the back side of FIG. The die 14 has an upwardly concave mold portion 16 and an end portion of the molded member 110 that give a predetermined shape to a member to be molded 110 and a composite material 112 to be molded, which are arranged on the upper surface of the die 14. It has a jig (for example, a vise) for fixing (not shown).

上部構造１２は、図１の手前側から奥側に向かって伸びる、下向きの凸形状を略中央部に有する直方体形状の剛性の高いパンチ１８を備える。このパンチ１８は、該パンチ１８の下方に配置される被成形部材１１０と複合材料１１２に所定の形状を与える、下向きに凸形状の型部２０を有する（図示せず）。 The superstructure 12 includes a rectangular parallelepiped-shaped highly rigid punch 18 having a downward convex shape in a substantially central portion extending from the front side to the back side of FIG. The punch 18 has a downwardly convex mold portion 20 that gives a predetermined shape to the member 110 to be molded and the composite material 112 arranged below the punch 18 (not shown).

パンチ１８は、図示しないパンチホルダによって保持されている。パンチホルダは、空圧式又は油圧式の昇降装置２２に連結されている。したがって、パンチ１８は、昇降装置２２の駆動に基づいて、図１に示す上昇位置と後述する図３に示す下降位置との間を移動するように構成されている。 The punch 18 is held by a punch holder (not shown). The punch holder is connected to a pneumatic or hydraulic lifting device 22. Therefore, the punch 18 is configured to move between the ascending position shown in FIG. 1 and the descending position shown in FIG. 3, which will be described later, based on the drive of the elevating device 22.

上述した実施形態において、パンチ１８は、パンチ１８の内部に設けられている伝熱部２４を備える。この伝熱部２４は、型部２０に沿う下向きの凸形状２６と、パンチ１８の下面に沿って左右に伸びる形状２８Ｒ，２８Ｌを有する。また、伝熱部２４は左右の端部で電源３０に電気的に接続され、後述する熱硬化性接着剤１１４が硬化できる高温を発するように構成されている。 In the above-described embodiment, the punch 18 includes a heat transfer unit 24 provided inside the punch 18. The heat transfer portion 24 has a downward convex shape 26 along the mold portion 20 and shapes 28R and 28L extending to the left and right along the lower surface of the punch 18. Further, the heat transfer portion 24 is electrically connected to the power supply 30 at the left and right ends, and is configured to emit a high temperature at which the thermosetting adhesive 114 described later can be cured.

［１．２：成形方法］
図１を参照して、上述の構成を有するプレス成形装置１００を用いた成形方法の一例を説明する。実際の成形にあたって、図の手前側から奥側に向かって伸びる直方体形状の被成形部材１１０はダイス１４の上面に配置される。実施形態において、図の手前側から奥側に向かって伸びるプレート状の複合材料１１２が被成形部材１１０の上面の略中央部に載せられる。また、熱硬化性接着剤１１４が被成形部材１１０と複合材料１１２との間で、複合材料１１２の下面全体に塗布されている。 [1.2: Molding method]
An example of a molding method using the press molding apparatus 100 having the above-described configuration will be described with reference to FIG. In the actual molding, the rectangular parallelepiped-shaped member 110 to be molded extending from the front side to the back side in the drawing is arranged on the upper surface of the die 14. In the embodiment, a plate-shaped composite material 112 extending from the front side to the back side in the drawing is placed on a substantially central portion of the upper surface of the member 110 to be molded. Further, the thermosetting adhesive 114 is applied between the member to be molded 110 and the composite material 112 on the entire lower surface of the composite material 112.

図２に示すように、複合材料１１２は被成形部材１１０の上面から上方に向かって順番に第１の部材１１６、補強部材１１８及び第２の部材１２０を有する。実施形態において、第１の部材１１６は図の手前側から奥側に向かって伸びるプレート状の部材である。この第１の部材１１６と被成形部材１１０との間で、電食が容易に発生しないように、第１の部材１１６と被成形部材１１０の材質は同じであることが好ましい。補強部材１１８は綱又は紐のような複数のストランドからなり、図の手前側から奥側に向かって配置され、第１の部材１１６の上面におけるダイス１４の型部１６に対応する、二点鎖線で示される領域１２２（図１参照）内に載せられる。また、熱硬化性接着剤１２４が補強部材１１８を覆うように、第１の部材１１６の上面全体に塗布されている。第２の部材１２０は、図の手前側から奥側に向かって伸びるプレート状の部材で、熱硬化性接着剤１２４に上方から接着している。実施形態では、第１の部材１１６の幅は第２の部材１２０の幅と同一又はほぼ同一である。したがって、第１の部材１１６は、その全面が補強部材１１８と熱硬化性接着剤１２４を挟んで第２の部材１２０のほぼ全面に対向している。 As shown in FIG. 2, the composite material 112 has a first member 116, a reinforcing member 118, and a second member 120 in this order from the upper surface of the member to be molded 110 upward. In the embodiment, the first member 116 is a plate-shaped member extending from the front side to the back side in the drawing. It is preferable that the materials of the first member 116 and the member 110 to be molded are the same so that electrolytic corrosion does not easily occur between the first member 116 and the member 110 to be molded. Reinforcing member 118 consists of a plurality of strands such as ropes or strings, arranged from the front side to the back side in the drawing, and corresponds to the die portion 16 of the die 14 on the upper surface of the first member 116. It is placed in the area 122 (see FIG. 1) indicated by. Further, the thermosetting adhesive 124 is applied to the entire upper surface of the first member 116 so as to cover the reinforcing member 118. The second member 120 is a plate-shaped member extending from the front side to the back side in the drawing, and is adhered to the thermosetting adhesive 124 from above. In the embodiment, the width of the first member 116 is the same as or substantially the same as the width of the second member 120. Therefore, the entire surface of the first member 116 faces almost the entire surface of the second member 120 with the reinforcing member 118 and the thermosetting adhesive 124 interposed therebetween.

上述のように被成形部材１１０及び複合材料１１２を配置した状態で昇降装置２２が駆動することで、パンチ１８はダイス１４に向かって下降する。その結果、被成形部材１１０及び複合材料１１２は、パンチ１８によりダイス１４に押し付けられることで変形する（図３及び図４参照）。このとき、型部１６，２０に対応する下向きの凸形状１２６，１２８が被成形部材１１０及び複合材料１１２に付与される。 When the elevating device 22 is driven with the member to be molded 110 and the composite material 112 arranged as described above, the punch 18 descends toward the die 14. As a result, the member to be molded 110 and the composite material 112 are deformed by being pressed against the die 14 by the punch 18 (see FIGS. 3 and 4). At this time, the downward convex shapes 126 and 128 corresponding to the mold portions 16 and 20 are applied to the molded member 110 and the composite material 112.

また、パンチ１８が複合材料１１２に接触しているとき、伝熱部２４はパンチ１８と複合材料１１２を介して熱硬化性接着剤１１４に熱を与える。その結果、熱硬化性接着剤１１４は硬化し、被成形部材１１０と複合材料１１２は接合する。 Further, when the punch 18 is in contact with the composite material 112, the heat transfer unit 24 applies heat to the thermosetting adhesive 114 via the punch 18 and the composite material 112. As a result, the thermosetting adhesive 114 is cured, and the member to be molded 110 and the composite material 112 are joined.

上述の方法で被成形部材１１０と複合材料１１２が接合することにより、成形部材１３０が得られる。 The molded member 130 is obtained by joining the molded member 110 and the composite material 112 by the method described above.

上述した実施形態において、例えば、被成形部材１１０は鉄から構成される。一方、複合材料１１２の第１の部材１１６は、約０．３ｍｍの厚みを有する鉄のプレートで構成される。補強部材１１８は、多数のカーボンファイバ（単繊維）を束ねた長繊維束の多数のフィラメントからなる約０．２ｍｍの径を有するトウを複数並列配置して構成される。第２の部材１２０は、約０．３ｍｍの厚みを有するアルミニウムのプレートで構成される。この場合、複合材料１１２は約０．８ｍｍの厚みを有する。第１の部材１１６と補強部材１１８と第２の部材１２０が有する厚み又は径を適宜調整することで、複合材料１１２の厚みは０．０１ｍｍ〜１ｍｍの間、好ましくは０．１ｍｍ〜１ｍｍの間で調整される。 In the above-described embodiment, for example, the member 110 to be molded is made of iron. On the other hand, the first member 116 of the composite material 112 is composed of an iron plate having a thickness of about 0.3 mm. The reinforcing member 118 is configured by arranging a plurality of tows having a diameter of about 0.2 mm composed of a large number of filaments of a long fiber bundle in which a large number of carbon fibers (single fibers) are bundled in parallel. The second member 120 is composed of an aluminum plate having a thickness of about 0.3 mm. In this case, the composite material 112 has a thickness of about 0.8 mm. By appropriately adjusting the thickness or diameter of the first member 116, the reinforcing member 118, and the second member 120, the thickness of the composite material 112 is between 0.01 mm and 1 mm, preferably between 0.1 mm and 1 mm. Adjusted with.

上述の構成を有する複合材料１１２は、補強部材１１８と熱硬化性接着剤１２４が有する弾性率によって、他の部品に接合されることで該部品の減衰能を向上させる効果を有する。したがって、被成形部材１１０と複合材料１１２が接合することにより得られる成形部材１３０は大きな減衰能を有する。 The composite material 112 having the above-described configuration has an effect of improving the damping ability of the component by being joined to another component by the elastic modulus of the reinforcing member 118 and the thermosetting adhesive 124. Therefore, the molded member 130 obtained by joining the member to be molded 110 and the composite material 112 has a large damping ability.

上述した実施形態において、被成形部材１１０と複合材料１１２の第１の部材１１６は、鉄以外の金属材料、例えばアルミニウム又は樹脂であってもよい。電食が容易に生じないように、被成形部材１１０と複合材料１１２の第１の部材１１６の材質は同一であることが好ましい。また、複合材料１１２の補強部材１１８は、カーボンファイバ以外の繊維材料、例えばガラス繊維であってもよい。 In the above-described embodiment, the member 110 to be molded and the first member 116 of the composite material 112 may be a metal material other than iron, for example, aluminum or resin. It is preferable that the material of the member 110 to be molded and the material of the first member 116 of the composite material 112 are the same so that electrolytic corrosion does not easily occur. Further, the reinforcing member 118 of the composite material 112 may be a fiber material other than carbon fiber, for example, glass fiber.

また、鉄のプレートからなる第１の部材１１６とアルミニウムのプレートからなる第２の部材１２０は約０．３ｍｍの厚みをそれぞれ有しているが、約０．０８ｍｍの厚みをそれぞれ有してもよい。また、補強部材１１８のトウは約０．０５ｍｍの径を有してもよい。この場合、複合材料１１２は約０．２ｍｍの厚みを有する。複合材料１１２が有する厚みが小さければ、被成形部材１１０がさらに微細な形状を有している場合でも、複合材料１１２は被成形部材１１０に容易に接合され得る。 Further, the first member 116 made of an iron plate and the second member 120 made of an aluminum plate each have a thickness of about 0.3 mm, but even if each has a thickness of about 0.08 mm. Good. Further, the toe of the reinforcing member 118 may have a diameter of about 0.05 mm. In this case, the composite material 112 has a thickness of about 0.2 mm. If the thickness of the composite material 112 is small, the composite material 112 can be easily joined to the member 110 to be molded even when the member 110 to be molded has a finer shape.

第１の部材１１６と第２の部材１２０、及び被成形部材１１０と複合材料１１２が接合するように、熱硬化性接着剤１１４，１２４が用いられているが、他の接着剤、例えば感圧型接着剤（粘着剤）が用いられてもよい。この場合、接着剤を加熱する必要はなく、上部構造１２は、伝熱部２４、凸形状２６、形状２８Ｒ，２８Ｌ、及び電源３０を必要としない。 Thermosetting adhesives 114 and 124 are used so that the first member 116 and the second member 120, and the member 110 to be molded and the composite material 112 are bonded, but other adhesives such as pressure sensitive type are used. An adhesive (adhesive) may be used. In this case, it is not necessary to heat the adhesive, and the superstructure 12 does not require a heat transfer portion 24, a convex shape 26, shapes 28R, 28L, and a power supply 30.

［１．３：他の実施形態］
上述した実施形態において、第１の部材１１６と第２の部材１２０が熱硬化性接着剤１２４により接合することで、複合材料１１２が得られる。一方、熱硬化性接着剤１２４ではなく、例えば爆発圧接などにより、第１の部材２１０と第２の部材２１２が補強部材２１４を挟んだ状態で、第１の部材２１０と第２の部材２１２を接合することで複合材料２１６を得てもよい（図５参照）。この場合、第１の部材２１０と第２の部材２１２の接合界面には特徴的な波状模様２１８が表れる。また、複合材料２１６は、他の部品に接合されることで該部品の機械的強度（耐力（破壊強度）と剛性（変形強度、ヤング率）の両方を含む。）を向上させる効果を有する。したがって、被成形部材と複合材料２１６が接合することにより得られる成形部材は大きな機械的強度を有する。 [1.3: Other Embodiment]
In the above-described embodiment, the composite material 112 is obtained by joining the first member 116 and the second member 120 with a thermosetting adhesive 124. On the other hand, instead of the thermosetting adhesive 124, the first member 210 and the second member 212 are held in a state where the first member 210 and the second member 212 sandwich the reinforcing member 214 by, for example, explosive welding. Composite material 216 may be obtained by joining (see FIG. 5). In this case, a characteristic wavy pattern 218 appears at the joining interface between the first member 210 and the second member 212. Further, the composite material 216 has an effect of improving the mechanical strength (including both proof stress (breaking strength) and rigidity (deformation strength, Young's modulus)) of the component by being joined to another component. Therefore, the molded member obtained by joining the member to be molded and the composite material 216 has a large mechanical strength.

上述した実施形態において、被成形部材１１０と複合材料１１２は熱硬化性接着剤１１４により接合するが、例えばパンチ１８が加える圧力による圧入で接合されてもよい。 In the above-described embodiment, the member 110 to be molded and the composite material 112 are bonded by the thermosetting adhesive 114, but may be bonded by press fitting by, for example, the pressure applied by the punch 18.

上述した実施形態において、複合材料１１２は被成形部材１１０の上面の略中央部に載せられているが、パンチ側に配置されていてもよい。この場合、複合材料が落下しないように、治具（例えば上下に摺動可能なホルダ）が複合材料の端部を支持していることが好ましい。 In the above-described embodiment, the composite material 112 is placed on the substantially central portion of the upper surface of the member to be molded 110, but may be arranged on the punch side. In this case, it is preferable that a jig (for example, a holder that can slide up and down) supports the end portion of the composite material so that the composite material does not fall.

上述した実施形態において、被成形部材１１０と複合材料１１２はダイス１４側からパンチ１８側に向かって順番に配置されているが、パンチ側からダイス側に向かって順番に、すなわち逆転して配置されてもよい。 In the above-described embodiment, the member to be molded 110 and the composite material 112 are arranged in order from the die 14 side to the punch 18 side, but are arranged in order from the punch side toward the die side, that is, reversed. You may.
